Dual Source CT Scanner

What is a dual-source CT scan?

All computed tomography (CT) scans use x-rays to quickly create cross-sectional pictures of your body. A dual-source CT scan uses two x-ray sources at right angles to each other. This doubles the speed of the test so you receive less radiation, and it also creates sharper images. A dual-source CT scan can be used to guide a surgeon to the right area, to identify tumors, or to study blood vessels.

What can I expect?

We will do everything we can to make you comfortable. You'll be asked to lie on a table, on your stomach, back or side. The table slides into the center of the CT scanner, where an x-ray beam will rotate around you.

Sometimes a CT scan requires a special dye, called contrast material, to highlight a specific area and create a clearer image. If your scan uses the contrast, you'll either receive it through a hand or forearm vein or else be asked drink it.

FAQs

How should I prepare?

If contrast material will be used, it's very important to tell the doctor if you're allergic to iodine or seafood, or if you have kidney problems.

You may be asked not to eat or drink anything for 4 to 6 hours before the test.

Take your usual medications unless your doctor says not to. Talk to your doctor if you take any blood thinners that would affect bleeding (Coumadin/Warfarin, Pradaxa).

You will be asked to remove jewelry and wear a hospital gown during the scan.
